note 86424 deleted from function.floor by danbrown

Note Submitter: mike dot devise at gmail dot com ---- marc at moblaster's rounding technique for handling financial truncation fails for 0.0, and probably has unintended consequences for values less than 0. Something like this should do the trick: function truncateMoneyFloat($amount) { if ($amount > 0.005) return round($amount - 0.005,2); elseif ($amount < -0.005) return round($amount + 0.005,2); else return 0.0; } However, +1 billion for jolyon at mways' comment regarding abandoning floats entirely when processing financial data. Create a money class and track the value internally with an integer. Provide methods to scale by float values where the rounding behavior can be controlled by an explicit policy variable.
